Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) Vice-President Dr John Tait said: “Voluntary fortification has not been sufficient, and with strong and compelling evidence that fortification of the wheat flour used to make bread reduces neural tube defects in babies, RANZCOG congratulates the Government for introducing mandatory fortification.”
